Abstract

The invention discloses a wave preventing method including steps of wave elimination and energy consumption by a main mode of wave energy conversion, and further provides a breakwater system using the wave preventing method. In the system, the upper end of an annular two-way hydraulic damper is fixedly connected with a floater; parallel steering shafts are arranged on the front and back end surfaces of main floating bodies; the tail ends of the steering shafts are fixedly connected with a floater winding shaft; at least two blade connecting rods are linearly fixed on the left and right two sides of the main floating bodies; rotating shafts are rotationally connected between each pair of adjacent blade connecting rods; an anchor chain is mounted on the blade connecting rod at the lowest part, and is buckled with an anchor; blades are mounted between the left and right symmetric rotating shafts on all the main floating bodies; each pair of adjacent main floating bodies are spherically connected through spherical hinges; hydraulic oil dampers are arranged between the main floating bodies; and hydraulic damper connecting bases and piston rods are mounted on the hydraulic oil dampers. The system has the effects of high safety and good wave eliminating effect.

Description

technical field [0001] The invention relates to the field of marine engineering safety, in particular to a wave prevention method and a breakwater system using the above wave prevention method. Background technique [0002] At present, floating breakwaters are usually wave prevention and wave dissipation facilities composed of floating components and mooring systems, and are often used in harbors, offshore construction sites, and mariculture and other areas. Especially in open sea areas, there are more and more marine cage cultures, and the cages are often damaged due to the invasion of typhoons and waves. In order to ensure the safety of aquaculture cages and the growth of cultured fish, it is very meaningful to eliminate waves and reduce currents in aquaculture cages through floating breakwaters. [0003] The configuration of floating breakwater can be mainly classified into three types: pontoon type, buoy type and floating raft type. The wave-suppression mechanism of th...
